STOCKHOLM, Jan. 26 (Xinhua) -- China's railway network, already the world's longest, is developing at record high speed and is to be doubled soon, Swedish daily Svenska Dagbladet reported on Wednesday."China's goal is to connect all important cities with railway lines," the report said.Collaborating with German Siemens, Japanese Kawasaki and Bombardier both in Canada and Sweden, China has built its own high-speed train CRH380A that can reach 486 kilometers per hour, cutting the journey between Beijing and Shanghai in half to about 4 hours.Construction of the high-speed railway network will also cover inland China, the report said. It aims to encourage more investment to move from coastal areas to inland China and ultimately raise the living standards in those regions.Within the next five years, a total of 3.5 trillion yuan (over 500 billion U.S. dollars) will be invested in high-speed track construction and train manufacturing, averaging at about 700 billion yuan (over 100 billion dollars) each year.Swedish companies such as Atlas Copco, SKF and Trelleborg have participated in China's railway and high-speed train development, according to the report.Hans Rosling, a development expert and also professor at Karolinska Institutet in Sweden, was quoted as saying that the construction of the high-speed railway network will bring about "good economy, good education, good medical care, better and longer life, all good things."

CARACAS, March 30 (Xinhua) -- The number of confirmed cases of the A/H1N1 influenza in Venezuela has risen to 482 this year, Health Minister Eugenia Sader said on Wednesday.According to the latest report, the state of Merida in southeastern Venezuela has 189 A/H1N1 influenza cases, the biggest number ever reported, which was followed by the Capital District of Caracas with 112 cases. The other 181 cases were confirmed in 17 of 24 Venezuelan states.The first case for this year was reported in Merida earlier this month.Sader said that the Venezuelan government was trying to prevent the spread of the disease. Some 3 million people have been vaccinated against the virus.Three patients infected with the A/H1N1 influenza virus have died in the country this year, according to Sader.The A/H1N1 influenza can cause deadly pneumonia if it is not treated early.

LOS ANGELES, May 12 (Xinhua) -- A subsurface ocean of molten or partially molten magma exists beneath the surface of Jupiter's volcanic moon Io, the Jet Propulsion Laboratory (JPL) said on Thursday."The finding heralds the first direct confirmation of this kind of magma layer at Io and explains why the moon is the most volcanic object known in the solar system," JPL said in a press release posted on its website.The finding was based on new data analysis from NASA's Galileo spacecraft, said JPL.The research was conducted by scientists at the University of California, Los Angeles; the University of California, Santa Cruz;, and the University of Michigan, Ann Arbor. The study is published this week in the journal Science, JPL said."Scientists are excited we finally understand where Io's magma is coming from and have an explanation for some of the mysterious signatures we saw in some of the Galileo's magnetic field data," said Krishan Khurana, lead author of the study and former co- investigator on Galileo's magnetometer team at UCLA."It turns out Io was continually giving off a 'sounding signal' in Jupiter's rotating magnetic field that matched what would be expected from molten or partially molten rocks deep beneath the surface."Io produces about 100 times more lava each year than all the volcanoes on Earth, according to data released by JPL in Pasadena, Los Angeles.While Earth's volcanoes occur in localized hotspots like the "Ring of Fire" around the Pacific Ocean, Io's volcanoes are distributed all over its surface, JPL said, adding that a global magma ocean about 30 to 50 km beneath Io's crust helps explain the moon's activity."It has been suggested that both the Earth and its moon may have had similar magma oceans billions of years ago at the time of their formation, but they have long since cooled," said Torrence Johnson, a former Galileo project scientist based at JPL, an affiliation with NASA."Io's volcanism informs us how volcanoes work and provides a window in time to styles of volcanic activity that may have occurred on the Earth and moon during their earliest history," said Johnson, who was not directly involved in the study.NASA's Voyager spacecraft discovered Io's volcanoes in 1979, making that moon the only body in the solar system other than Earth known to have active magma volcanoes. The energy for the volcanic activity comes from the squeezing and stretching of the moon by Jupiter's gravity as Io orbits the largest planet in the solar system.Galileo was launched in 1989 and began orbiting Jupiter in 1995. Unexplained signatures appeared in magnetic field data from Galileo flybys of Io in October 1999 and February 2000. After a successful mission, the spacecraft was intentionally sent into Jupiter's atmosphere in 2003.

BEIJING, Feb. 21 (Xinhua) -- China's domestic air travelers, as well as international passengers in and out of China, will be the biggest boost to airline industry growth over the next four years, according to an industry outlook report by the International Air Transport Association (IATA) Monday.Of the world's expected 800 million new travelers by 2014, about 181 million new passengers will come from China's domestic air routes, while another 33 million will be passengers flying to or from China via international routes, IATA said.China's 181 million domestic air passengers growth will lift the country's domestic passenger throughput to 379 million by 2014, only behind the United States in the world's aviation traveler volume ranking, according to IATA.The United States will remain the largest single country market for domestic passengers, with 671 million domestic air travelers and international passengers by then, according to IATA's forecast.The world's air travelers will top 3.3 billion by 2014, up by 800 million from the 2.5 billion in 2009, while world air cargo will rise to 38 million tonnes from 26 million tonnes in 2009."The forecast indicates that the world will continue to become more mobile. This creates enormous opportunities but also presents some challenges," Giovanni Bisignani, IATA' s Director General and CEO, said in the outlook report."We will need even more efficient air traffic management, airport facilities and security programs," he said, adding the shadow of the global economic recession is expected to remain over parts of the industry for some time to come.He said lingering consumer debt, high unemployment and austerity measures will dampen growth rates in Europe and North America, shifting the industry's focus eastwards.By 2014, 1 billion people will travel by air in the Asia-Pacific region, accounting for 30 percent of the global total, up from 26 percent in 2009, he added.

BEIJING, Feb. 12 (Xinhua) -- A delegation of the Chinese People's Political Consultative Conference (CPPCC) left Beijing Saturday evening to visit Ghana, Rwanda and Mozambique.The delegation, led by Vice Chairman Li Zhaozhuo of the CPPCC National Committee, was invited by the Parliament of Ghana, the Rwandan Chamber of Deputies and the Parliament of Mozambique.
